' My invention has for its object the production of a combinedagricultural implement containing a cu-ltivater, seedcr, corn-planter,and hay-rake, each of which shall be simple in construction, easy andellicent in operation, and by having in common the frame, seedhox,operating' devices, dec., can be furnished at a much lower cost than ifseparate; to which-end,

It consists, rst, in the construction and arrangement of the permanentframe, as is hereinafter set forth.

It furtherconsists in the means employed for irnparting a lateralmot-ion to cultvator-hars, and for actuating the dropping devices of thecorn-planter, as is hereinafter specified, vIt further consists in themeans employed for adjusting vertically the cultivator-bars andcorn-planting devices, and for tripping the rake-head, as is hereinafterdescribed.

In order to better illustrate the construction and operation of mymachine I will describe separately each arrangement of the same.

In iig. 1 of the annexeddrawingf4 A represents the axle-tree, havingpivoted npbnlits ends two ground-wheels, B and B', the journals a forvhich are dropped below said axle, as shown in Secured at their rear'ends upon the lower side of the axle A are two bars, O, which fromthence project forward and slightly inward, and are connected together'byneans of two cross-hars, I) and E, the first of which is secured uponthe-lower side of said bars C, at or near their fr ont ends, while thelatter is secured'iu-a like manner -neartheirfentea-longitudinally, thewhole .forming the permanent frame of the machine. A

F, F, and F, represent three bars, pivoted at their front ends to thelower side of the axleA, near its ends and at its centerfrom whence theyextend rearward'in parallellines and are connected togetherby means of across-bar, G, resting upon their upper lsjides, and secured loosely' toeach by 'means of a olt,`g.

lwo other bars, "H, corresponding in dimensions with the bars F, arepivoted loosely to the cross-bar E, and from thence extending rearwardparallel with and equidistant from said bars, are connected together' bymeans of a cross-bar, I.

Two short cross-bars, K, secured at their outer ends beneath the bars F,and at their inner ends upon two blocks, k, form a guide through whichthe rear ends 4of the bars H extend, and by means of which the latter,while allowed free lateral motion, are retained in the same vertical.plane as are the bars F. Y

Each of the bars F and H has pivoted to its rear end the upper end of ashort bar, L, to the lower end of which is attached a shovel, M, ofusual form.

A metal brace, N, connected to each of the hars L ata point midwaybetween its ends, and to the bars F or H at an equal distance from theirpoint of intersect-ion wit-h said bar L, furnishes a means wherebyV thedesired forward inclination of the latter may be secured and maintained,to accomplish which result the upper end of cach brace is provided witha series i of holes for the reception of the connecting-bolt n, so as toallow said brace to be shortenedl or lengthened.

In order that the shovels may be raised or lowered when desired, ashaft, O, suitabl journaled within metal bearings P, attached to theupper side of the axle A, is provided with two arms, o, which extend einan.:

radially outward and to the rear in the same piane, and arecona'ectecll` to the .bars hl by means ot twometal reds, (3,. so thatwhen said shaft le partiallyy rotated, the radial motion oi' said armscommunicates a corresponding'vertical motion to said hars and theshovels.

A lever, it, secured to and projecting upward from 'the shaft 0, hasupon one, side a detent, S, so arranged as to slide longitudinallywithin a hearlngf'r, and engage at its lower end withone of a series ofnotches, ,t 'provided.withi1 x the edge of a segment, (il, and

thereby lock said lever in position.

A short seniicireularlever, U, pivoted to the lever lt, near its ripperend, and loosely connected at one end to the upper end ofthe detent-rodS, furnishes a means whereby said detent may be released 'from`engagement with thcsegment, when desired, while a spring, u, secured tosaid lever R and pressing against the upper end of said lever U, securesthe engpgement of said detent when not purposely released.

When used for cultivating corn, the rear center shovel is removed and ametal shield,.V,' having the form shown in hg. 2, is secured to themachine l'oyy means of a V-shaped brace, lV, attached 'at its center tosaid shield andv at its ends to the bar H, irnmediately in rear of theaxle.

rllwo foot-levers, X, pivoted at theirfront ends tothcreross-bar E, andprojecting beneath and to the rear of thel axle A,arc each connected tothe vbars H by means of a chain, Y, which' passes upward around apulley,y, secured upon the .real side .of said axle, outward around a secondpulley, y, placed near the cud of said axle and from thence extendinginward has its end fastened to or upon said bar H.

A seat, Z, secured upon the rear end. of a bar, A', that is attached atits front end to a cross-bar, D, and rests within a metal crotch, B',extending upward from the axle, completes the device, the opera-tion ofwhich is as follows:

The operator being in position upon the seat Z, astride of the bar A',with his feet upon the foot` levers X,jand the machine driven forward,the' vertical adjustment of the shovels is secured 'hy'inen's of thelever lt, while, by means of said ibut-levers operating through thechains Y and bars H, the shield V isso guided as Ato cause it4 topass`directly-over a row of corn and protect it from the soil turned upby the. front shovels, which soil would otherwise cover and injure theyoung corn.

The especial. advantages possessed by this device are thatby it theoperator is enabled to readily adjust and maintain the vertical positionof the shovels,regai-dices of the inequalities of the ground, and incultivating corn he can so guide the shield and contiguous shovels as tocause them to protect and operate upon a row in the most perfectmanner.

For use as a feeder, the shield V, foot-levers X, and chains Y areremoved, and a seed-box or hopper, U', with its operating devices,added.

As secu in iig. 4, the seed-box C', having the usual V-shape,transversely, is placed between Vthe cross-bars D and E, the inner edgesol' which conform to and-tit against the sides of said box, so as tohold. it firmly in position immediately beneath the bars (l.

A series of openings, c', corresponding in number and inposit-ion,transversely, with thc-shovels M, are provided in and through thebottoni of the seed-box, and have placed over each a wedge-shaped cover,D', which prevents seed from passing directly from the. box.

Resting. upon the real bottoni of.' the seed-box, beneath the cover D,is a false or movable bottom, E', in and through which are a number ofopenings, e', corresponding lin size andrelative position with thosewithin seid real bottom, by which means said movable bottom or slide mayhe adjusted lengthwise, so as to cause said openings to coincide andpermit the con tents.. of those within the slide E to he dischargedthrough those within the bottom, or, by changing they position of theslide, all passage of 'seed may he prevented.

4Inni-der that the size-of the openings c' may be changed. so as tocorrespondingly vary the quantity of grain sown, the upper face oftheslide iscovered by'a plate et' sheet-metal, F', in ,and through which iscut a number of openings, f', corresponding in size and position tothoscwithin said slide.-

Allange, f', corresponding in width to the width of theopening and inlength Vto the thicknessofthe slide E', is turned downward from'v themetal lplate E' into the; opening e', so that, if said plate .F' bemoved lengthwise of said slide, said opening e' will not only be'shortened'or. lengthefned, but theiusides-will be at all times vertical.j

The'longitudinal adjustment of the slide E' and plate F 'is secured' bymeans of a set-screw, e", which is' joui ufiled within a flange, f,projecting downward .i'oin'the end of said plate,` andjcxtends 4into asuitable nut within the end vof said' slide, so that by turning saidscrew said slide is moved to and from-said flange.

-For use while sowing oatsa'rod, G', is secured within the upper face'of the slide. E', niidwaybetween the.

openings e', and, passing 'vertically upward through suitable 4slotswithin the plate E', s erves to agit-ate. saidoat-s', so as to preventthem from cloggi'ng 'within the hopper. l v

The slide E is operated by means of thefollowingf described devicesz. A1

A lever, H',`is pivot-ed n on the end oftheseed-box, and looselyattached at its l wer end to the outer end of saidslidel A second lever,1', pivoted at @s center to a brace, K', attached to the upper side ofthe'axle,and loosely connected at its forward end tothe upper end of.the

lever-H', is provided at its rear cnd with a stud, i',

which passes downward 'into a serpentine groove, l', formed -upon orwithin -the periphery of .the disk L,

attached to and revolving within the inner end of the hub of one of thetraction-wheels, so that a rotan;r motion of said wheel will producea'nniform' reciprocating movement ofthe slideand cause the openingscontained'therein to he regularly iilled with seed and dischargedthrough tho openings within the bottom'ofthe seed-box.

In order that thcinotion ofthc'sowiug devices may be arrest-ed whendesired, a short lever, M', ispivoted upon the upper side oftl1e'axle,and has' its iuterend loosely attached to the rear end of' thelever 1, so that bypressiug downward with his foot hlipon the inner endoi' said lever M', the operator can raisegs'aidleverl' sudiciently torelease the stud i' from engagement with. the groove l'.

Upon releasing the lever M 'it is drawn upwardl by means ota spring, m',placed beneath its inner end, andthe stud i' caused to engage againwiththe slot l.

In .most of the wheat sown a certain proportion of oats is found thathas escaped the devices used for their removal.

To prevent said oats from passing into the ground with the wheat, Iemploy 'a screen formed o f two sheets of reticulated metal, N, securedat' their rearl side and at their ends to suitable bars of wood, n',sons toleave between a space open to the front. l

The bar n', secured tothe rear of the screen, extends semewhat above theupper plate, so as to form a ledge which prevents the grain from passingfrom the rear side of said plate.

seed-box, while its-rear edge -is upheld and adjusted vertically bymeans of a chain,-P, passing upward from said separator through astaple, p', projecting from the side of the bar A', and having its endpassedover a studa, projecting upward from the upper side of the bar.

The separator N is onlyemployed when sowing wheat containing oats, atwhich time its operation is as follows: l

The grain discharged from the seed-box is caught by the separator,which,having a reciprocating move# ment, longitudinally, shakes saidgrain quickly iu opposite directions, by which means the wheat is causedto pass through the openings, while the oats, being larger and morerough, are retained upon the top of said separator and pass to the rearagainst the bar 'n'.

yThe inclination ot' the separator should be such as to cause the grainto pass across the same but not arrangement of the parts are case andthoroughness of operation combined with durability. v

For use as a hay-rake, the wheels, axle, main frame, composed of thebars C and cross-bars D and E, and the shaft 0, with its attachment, areemployed, to which is attached the supporting-frame for the rakehead,consisting of two bars, Q', pivoted at their front ends to the bars C,and connected together at their rear ends byvmeans of n. eross-bar,-R.

lhc rake-head S', having a length somewhat greater than the breadth ofthe machine over the wheels, is loosely attached to the upper side ot'the cross-bar 1t at the point of intersection with the bars Q', and hasattached, at equidistant points upon its upper side, a number ot teeth,T', formed of [iat thin bars of metal bent in the shape shown infigs. Sand 9, so as to pass downward in front of and beneath said rake-head.

The point of each tooth, as seen in iig. 9, is shaped like acultivator-tooth.

Secured to and projecting rearward from the rakehead S' are two metalrods, U', having at their outer ends suitable eyes, to cach ot' which isloosely attached the rear ends ot` other rods, Y', having their frontends pivoted to or upon the arms o of the shaft 0.

As thus constructed and arranged a partial rot-ation of the shaft D willcause the rake-head to rock upon the cross-bar It', so as to elevate,the teeth and release their contents.

It. will be noticed that the transverse shape of the teeth is differentfrom any heretofore used, the object of which is to permit them to beemployed to assist' the cultilvator in removing weeds from the surfaceof the ground, in accomplishing which result both rake and cuitivatorare connected with the main frame, as shown in fig. 8. t

In tig. ll is shown the machine as arranged for planting corn, in whichthe -front ends of theouter bars F are extendedv somewhat forward of theaxle, so as to bring thc cross-bar G directly beneath the outer ends ofthe arms o, and permit t-l1e.rods Q to be connected therewith.

Each end of the hopper C' is mounted upon a conductor, W', withina.crotch formed by extending the front and rear sides w' of saidconductor upward and outward at a corresponding angle with the sides ofsaid hopper; and the whole is attached to the frame by means ot' a shortbar, X', secured to the rear fork of each crotch, to the rear side ofsaid hopper, and to the bar F.

A runner, Y', is pivoted at its front end to the corresponding endofeach bar F,'and from thence curving downward and to the frear,terminates in a vertically-divided or forked end, which incloscs 'and issecured to the lower end of the spout'or conductor W'.

A narrow ange, y', extending outward in a curve from each side ot' thebottom ot' the forked end of the ruimer Y', undercuts the soil in such amanner as to cause it to more readilyfali inward and cover the corn.

Pivoted to the rear side of4 each spout W in a semieylindreal plate, Z',placed with its concave side downward, as shown in igs.11 and 12, theobject of which t is to cover the soil over the comas it is deposited inthe furrow formed by the runner.

A spring, A", is secured, at its upper end, to the spout W', and fromthence extends downward and rearward over the covering-plate, upon whichsaid spring is caused to exerta downward adjustable pressnre by means ofa set-screw, a", passing downward through the rear end of the lat-terand bearing upon thc upper` side of -the former. l

As but the endfopenings iu the bottom of the sidebox are used for thepassage of corn, a sutieient space for containing a suppl y of thelatter is set apart at each cud ot` the box by means of a partition, B",having its edges fitted into corresponding grooves within the sides ofsaid box.

the corn, when desired, by means of a lever, C, pivoted, at its rearend, to the rear side of the seed-box, connected with the upper end ofthe lever H' by means of abar, D", and having attached toits front endthe a-nd the lever H', to the the runners, and, as the Amachine passesover the check-rows, by alternately depressing said footFlevers, dropsthe corn into the furrows, where it is covered by means of the eovererZ'.

As the varying condition ot' the soil may require, the pressure upon thecoverer is changed so as to cause it to perform its otlice withoutdragging the corn from the position in which it is deposited by thedroppingdevices.

Should a stone, hard mass of earth, or other obstruction, strike theeoverer, the yielding of the spring A" will he sni'licient to permitsaid cover to raise and pass such obstruction, instead ot' dragging t-helatter along upon the ground and destroying the regularity A of the rowsot corn, as is the case where t-he eoverer is rigidly attached.

As constructed and arranged one person can operate the corn-planter withease, certainty, and dispatch; and from the simplicity of its parts andthe readiness with which they can he adjusted, it is believed to be oneof the lmost desirable devices ever construete'd for this purpose.v

' Having thus fully setv forth the nature and merits of my invention, y

That I claim as new, and desire to secure by Letters Patent, is-

cousist-ing of the axle A, the side-bars O, and the cross-bars D and E,supported by and upon the wheels B, substantially as 4and for thepurpose specified.
